On Lisbon's cobblestone lanes, the Portuguese economy is hobbling along as it always has — in cash.
In a tiny, 100-year-old bar, Nuno Goncalves pours out glasses of ginja — a Portuguese sweet cherry liqueur — for his customers, mostly old men in flat caps. A small shot-glass full costs 50 cents — cash only. There is a cash register, but it doesn't print receipts.
When actor Philip Seymour Hoffman died of an overdose in February, the New York City medical examiner ruled that his death was the result of "acute mixed drug intoxication." Heroin, cocaine and a widely prescribed class of drugs known as benzodiazepines, or benzos, were found in his system.
Freight trains roll through the Chicago suburb of Barrington, Ill., every day, many pulling older tank cars known as DOT-111s. They're known as the "soda can" of rail cars, says village President Karen Darch, because their shells are so thin.
Many of the DOT-111s are full of heavy Canadian tar sands crude oil. Some carry ethanol. And more and more of them are loaded with light Bakken crude oil from North Dakota.
